The Fight for Gnomeregan.

It will be another Caverns of Time instance, where you travel back to Gnomeregan, just as the Troggs break through, and it’s up to you to repel them, or at the very least ensure that Gnomeregan is uninhabitable by setting off the radiation bomb at the request of Mekgineer Thermaplugg.

You will of course be “skinned” as Gnomes… no Humans, Elves, Draenei (maybe Dwarves… but Gnomes are best).

OK, nothing really special so far… so how about…

Only the Alliance get to be Gnomes!

Yep, this is a strictly Alliance only Instance.

Storming Gnomeregan!

Of course if you are Horde you get to run a slightly different version of the instance:

Storming Gnomeregan!

That’s right, you are not Gnomes… you are Troggs, the Troggs that are overrunning Gnomeregan.

You objective is to secure Gnomeregan before you are either:

Repelled, or

The Gnomes press the self destruct button making Gnomeregan uninhabitable.

Now, let’s throw in one more twist…

Gnomo e Troggo…

V

You may also enter this instance via the Battlemaster!

Yep, this can also be a new battleground.

Gnomes v. Troggs…

Gnomo e Troggo…

Same objective in mind, but now you are not just leading/fighting the opposing NPCs, but are also dealing with Player Characters.

What an awesome mix of:

Zerging NPCs and crafty PCs

Corridor combat and Open space combat

Features

In any mode you get XP and Rep, in the PvP mode you also receive Honor and marks.

You can gain power ups by controlling binary punch card machines

The alarm-bots will give the alliance warning of the approaching Horde or Alliance (but who knows whether they are NPCs or PCs?)

Both sides can gain access and use land mines

If you win, you gain control of the Clean Room and the vendors that go with it… which is the only way to redeem your Gnomeregan marks.

Ideally this can be run with multiple size groups, 5 man, 10 man, 25 man and even 40 man.

Sounds like a great concept. Would It be for level capped players? Or, would the instances be for the levels that are currently appropriate?
My biggest question, would I have to level a gnome mage to experience the ally version? The thought of having four fingers creeps me out.

A neat way to do this might be like what I heard Blizz was doing with heroics for WotLK (but ended up not doing apparently) – and keep normal instances as they are, but make heroic versions that take place in a different time frame – as you said, the invasion of Gnomeregan, or perhaps an invasion of Org through RFC.
